Do I Need To Acclimatise New Wood Floor?

This is one of the questions that is most frequently asked, and getting this right is the first step for a successful installation. The answer is (of course) ‘yes’ and ‘no’ – depending on the construction of the product you are using. So here’s a quick guide.
Engineered Floors

A real engineered three-layered constructed board should not be acclimatised, and should be fitted immediately after opening the box that it came in. The instructions will normally come in the box; if they don’t, you should call the supplier and check. An engineered board is usually delivered in a sealed box with a moisture content of approx 6-7% and, due to its construction and stability, should perform well under decent site conditions. Remember however that your installer should always check the site conditions with a hygrometer on the day of installation.
Multi Floors

Multi floors (also known as multi layered or semi solids) should be acclimatised. They are not truly engineered, and come with a moisture content of between 9-11% so care should be taken in checking site conditions before installation.

Generally the plywood base used in multi floors are incredibly stable and probably won’t move at all. The top layer however will want to move. As always, to be absolutely certain, check with your installer to see if acclimatisation is required.
EPH Certified Floor

These boards do not need any type of acclimatisation due to the manufacturing process. We have more information on EPH Floors in our Guide.
Solid Floors

Solid floors should always be acclimatised for a period of at least one week, and we recommend waiting longer.
Why is acclimatisation important?

Wood is what as known as ‘hygroscopic’. In plain English this means that it will, if surrounded by air containing more moisture than it does, absorb some of that moisture (and therefore expand). It will also lose moisture to air that is drier (and therefore contract). If a floor that needs acclimatisation is fitted before it has acclimatised then you could end up with either gaps or bulges in your floor.
